The web-gun? wielding spider didn't die when it was stopped while I read the description nor when touching green flies. Pressing Z fast enough made for a good machine-gun though. PS: Cursor-key support (the keys with an arrow) would be nice.
Yeah, I posted an update to the game a little bit ago, and I believe there have been some issues. Sorry about that. It will be fixed in the next patch, which I'll get out as soon as possible. :)
